Motorcycle builders and riders, this Badlands turn signal module is pure genius for cleaning up your handlebars and adding modern convenience to any bike! The ATS-03 module gives any custom build or older Harley (1973-1990 models) the self-cancelling turn signal feature that newer bikes come with standard. It features 9-second timed flashing that automatically shuts off, so you never accidentally leave your blinkers on down the highway. You can also manually cancel at any time, plus it has built-in emergency flasher mode for added safety. The solid-state flasher works with both regular bulbs and LEDs (up to 100 watts), and it includes a load equalizer so you don't need additional resistors. The module is surprisingly compact - about 2-7/8 inches long - so it tucks away neatly under your seat or in the headlight bucket. Installation is straightforward with the included wiring connectors and diagrams, though basic electrical knowledge helps. I installed one on my vintage Sportster and the difference is incredible - no more forgetting to cancel signals or dealing with bulky factory flasher relays. It makes any custom build feel more professional and modern. Perfect for cafe racers, choppers, bobbers, or anyone who wants that clean handlebar look without losing functionality. Seriously, once you ride with self-cancelling signals, you'll wonder how you ever lived without them!
